Answer:
x=7
Step-by-step explanation:
7=2x-7
-2x-7-7
-2x=-14
x=-14÷2
x=-7
Step-by-step explanation:
Well, this is a function. In order to solve this, you need a v value. Once you get a v value, you can plug into into 6+v^2 and wala- you get your answer.
Example, lets say
v is 3
then
F(3) = 6 + 3^2
f(3) = 6 + 9
f(3) =15

Answer:
1)20 000 000×12cm
240 000 000/100m
240 000 0/1000
2400km
31.6--1580×100×1000
31.6--1580 00 000
31.6/31.6--1580 00 000/31.6
1:5000000
A would equal 60 because you would divide 60 by 2 there for getting 30

Answer:
373248cm³
Step-by-step explanation:
first we need to find the value of the side length by plugging in the value of y and x
side length = 8x²y + y³
x = 1/2 and y = 4 ( plug in these values )
side length = 8(1/2)²4 + (4)³
we can evaluate using pemdas
p - parenthesis
e - exponents
md - multiplication and division ( left to right )
as - addition and subtraction ( left to right )
first we evaluate anything in the parenthesis if needed. its not needed though because there is no operations in the parenthesis
Then we evaluate exponents
side length = 8(1/2)²4 + (4)³
there are 2 so we evaluate them
(1/2)² = 1/4 and 4³ = 64
side length = 8(1/4)4 + 64
next we do the multiplication and division going left to right
8 * 1/4 = 2
(2)(4) + 64
2 * 4 = 8
side length = 8 + 64
finally the addition
side length = 72
No we want to find the volume of the cube
We can find the volume of a cube by simply cubing the side length
The cube has a side length of 72cm
so the volume is equal to 72³ = 373248cm³
